Abstract: FIELD: oil and gas wells. 
     SUBSTANCE: invention relates to equipment used for sealing the mouth of oil and gas wells during their construction, development and repair. The proposed preventer contains a one-piece casing with upper and lower flanges, having a through axial channel for the passage of pipes run into the well, two upper side channels located opposite to each other, oriented perpendicular to the axial channel and closed with side covers, and the lower lateral channel made under the upper channels and closed by its lateral cover, the axis of which is located at an angle to the axis of the upper channels. At the same time, a ram valve is placed inside the body, containing two oppositely located dies for sealing pipes along the outer diameter, installed in the upper side channels of the body with the ability to move in a direction perpendicular to the axial channel, and a movable gate plate designed to block the through axial channel in the absence of pipes in the well and installed in the lower lateral channel with the ability to move in a direction perpendicular to the axial channel. The BOP has one autonomous screw drive for each ram and one for the gate plate, installed in the corresponding side cover. On the outer side of the housing, in the area between the side covers, a recess is made, which, together with the removable cover and the gasket, forms a sealed heating chamber, while in the opposite corners of the removable cover, fixed to the housing with screws, there are two fittings for supplying and removing the coolant.
