Abstract
The utility model relates to a multifunctional anti-theft valve comprising a valve rod, a valve clack and a valve body, wherein the bottom end of the valve rod is provided with an anti-thrust ring; the valve clack is provided with a guide groove; one end of the valve rod, provided with the anti-thrust ring, is inserted in the guide groove; the upper end surface of the valve clack is provided with a valve clack gland; the anti-thrust ring is matched with the valve clack gland in a limit way; the other end of the valve rod, far away from the anti-thrust ring, is sheathed with a jacket fixed on the valve body; and an inlet and an outlet of the valve body are provided with threads used for connection with pipelines. In the utility model, the valve clack and the valve rod of the multifunctional anti-theft valve are slidably matched with each other, therefore the multifunctional anti-theft valve integrates the functions of shutoff, adjustment, return stopping and the like and solves the single-function problem of the traditional shutoff valve.
Description
Technical field
The utility model relates to valve technology field, especially a kind of multifunctional burglary-resistant valve.
Background technique
In the liquid medium pipeline is carried, during especially production wellhead liquid is carried, often need to the liquid that pipeline is carried end, different controls such as adjusting, connection, so need in pipeline, be connected in series stop valve; But, in the fluid course of conveying of production wellhead, also need to carry out non-return control, because the flap and the valve rod of present stop valve are fixed together, can only realize ending and regulatory function, therefore function singleness also must be connected in series check valve in pipeline; In actual mechanical process, need control respectively each valve, this has brought great inconvenience for staff's proper functioning, has also occupied bigger space and length of pipeline simultaneously.In addition, the form that the stop valve that is adopted in the existing oil line pipe mostly adopts flange to connect is connected with pipeline, makes fastener (bolt) exposed outside like this, suffers that very easily lawless person's theft destroys.
Summary of the invention
The purpose of this utility model is to provide a kind of multifunctional burglary-resistant valve, to solve the problem of existing stop valve function singleness.
In order to address the above problem, multifunctional burglary-resistant valve of the present utility model is by the following technical solutions: the multifunctional burglary-resistant valve, comprise valve rod, flap and valve body, the bottom of described valve rod is provided with the retaining ring, described flap is provided with guiding groove, the end that described valve rod has the retaining ring is plugged in the described guiding groove, and the upper-end surface of described flap is provided with the flap gland, described retaining ring and described spacing cooperation of flap gland; Described valve rod is arranged with the sheath that is fixed on the described valve body away from an end of described retaining ring; Be provided with in the import of described valve body and the outlet and be used for the screw thread that is spirally connected with pipeline.
Described valve rod and described sheath screw-thread fit.
The flap of multifunctional burglary-resistant valve of the present utility model cooperates with valve stem slides, thereby will be integrated by functions such as, adjusting, checks, has solved the problem of traditional stop valve function singleness.
Further, at the outside sheathed sheath of described valve rod, need to stretch into sheath and just can turn described valve rod with special tool; In addition, in the import and the outlet port of described valve body screw thread is set, thereby is spirally connected, do not have exposed link,, exist, can effectively prevent lawless person's pilferage behavior like this as connecting bolt with pipeline; Described valve rod and sheath screw-thread fit can be ended valve rod at any point when moving up and down valve rod easily so surely, are convenient to the flow in the control valve body.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view of valve rod among Fig. 1.
Embodiment
A kind of embodiment of multifunctional burglary-resistant valve of the present utility model, as depicted in figs. 1 and 2, be provided with screw thread on the import of valve body 5 and the inwall of outlet, has valve port between the import of valve body 5 and the outlet, be pressed with flap 4 on the plane at valve port place, flap 4 has one near a side of valve ports and is used for the sealing surface 6 that cooperates with sealing valve port, flap 4 has guiding groove away from a side of valve port, be fitted with valve rod 1 in the guiding groove, the bottom of valve rod 1 is provided with retaining ring 3 by screw, the outer circumferential face and the guiding groove of retaining ring 3 are slidingly matched, be bolted with flap gland 2 in the guiding groove, flap gland 2 cooperates with retaining ring 3 retainings, valve rod 1 is slidingly matched with flap gland 2 simultaneously, be bolted with bonnet 7 on the valve body 5, bonnet 7 and flap 4 corresponding settings, bonnet 7 is set with sheath 8 away from a side of flap 4, the end that sheath 8 is used for cooperating with bonnet 7 has an external thread section, has corresponding screw on the bonnet 7, sheath 8 and bonnet 7 are spirally connected and in being folded with sealing gasket between the two, has a nut segment 9 in its external thread section top on the sheath, has screw thread on the endoporus of nut segment 9, has corresponding thread section on the valve rod 1, the thread section screw-thread fit of valve rod 1 and sheath 8, valve rod 1 has valve rod working head 10 away from an end of flap 4, valve rod working head 10 adopts pentagon and all is in the sheath 8 on the limit inferior position thereon, needs just can open with special tool.The multifunctional burglary-resistant valve of present embodiment in use, the import of valve body 5 and outlet are spirally connected with corresponding pipeline respectively, cooperate with valve rod working head 10 by special tool and to turn valve rod 1, the pressure medium of valve body 5 inlets backs down flap 4, with the pipeline conducting, can regulate rate-of flow by turning valve rod 1 simultaneously; When inlet's pressure medium disappears, flap 4 hurtles down under action of gravity and cooperates with sealing valve port by its sealing surface 6, thereby realize the check function, need to realize when function, turn valve rod 1 and flap 4 is pressed down get final product, in addition, when when some in particular cases need reverse conducting, can move by turning on the valve rod 1 drive flap 4, thus the conducting pipeline; Because the valve body 5 of the multifunctional burglary-resistant valve of present embodiment is spirally connected with corresponding pipeline, the fastening piece that does not expose (as bolt), survivable, in addition, valve rod working head 10 is a pentagon, makes general utility tool to open, and has realized anti-theft feature, at valve rod 1 outside sheathed sheath 8, further strengthened anti-theft feature.
